Présentation
Full professor at Université de Lorraine since 2013, I carry out my research in LEMTA laboratory, a unit affiliated to CNRS. For one year in 2011, I was a fellow at the Center of Smart Interface in Darmstadt in the team of Pr Tropea. Before that, in 2000, I was a full-time researcher at the CNRS for 6 months, in order to initiate and develop research in the field of boiling applied to cooling systems, a new research field in LEMTA laboratory. Indeed, my main research area deals with two-phase flows with phase change and applies to many industrial issues (steel industry, nuclear safety, etc.) for which I have established long-term partnerships with major industrial groups or institutes such as CEA, IRSN and IRTM2P through national research programs (ANR) or European research ones (EURATOM) Before becoming deputy director of LEMTA in 2023, I have been leading for 3 years the research group, "Fluid media, rheophysics" within LEMTA which includes 4 research teams, 28 researchers, 18 PhD students and 2 post-docs with a budget of around 900k€/year. During 5 years (1/2019 to 12/2023), at the national level, I led GDR CNRS TRANSINTER (http://gdr2042-transinter.univ-lorraine.fr/), a research network of 23 laboratories, 6 industrial companies (ArcelorMittal, Vallourec, Constellium, Ariane Group, Renault Nissan Mitsubishi, Air Liquide) and 4 institutes (INRA, IRSN, CEA, ONERA). More than 200 researchers or industrials are members. This network provides researches on heat and mass transfers. I am now involved in as its deputy director. At international level, I signed a “co-tutelle agreement” with University of Campinas (UNICAMP, Brazil) for the supervision of Arlindo Theodoro de Souza Netto for the study of a transient boiling systems dedicated to the reduction of fuel consumption in the starting phase of cold engine (defended on 21th march 2025). I am also engaged in a project with University of Sao Paulo – San Carlos School Engineering. This project is led by Prof. Dr. Arthur Oliveira, a former postdoc in my research group and is dedicated to the study of heat and mass transfer within multiple droplet impingements on high temperature surface
